Mahouka Koukou no Rettousei - Double Seven-hen - Vol. 3 Ch. 20 - A Match for Pride (I)

[zerio]

i see so the manga releasee also the problem here eh

Yeah.

Spoiler: Succession and Ten Master Arcs

Another example is the vol 1 of Ten Master Arc (where it shows the reaction of everyone after it was announced that Tatsuya and Miyuki were part of Yotsuba) was published on September 2020.
Meanwhile, vol 3 of Yotsuba Succession arc (where Maya made the decision of revealing Tatsuya and Miyuki as Yotsuba) was published on May 2022.
Basically you got spoiled if you read Ten Master Arc on launch lol.

So yeah, it seems like the manga was intended for LN readers.
